To all whom it may concern Be it known that I, HERBERT S. VVILsoN,

' a citizen of the United States, residing at tained a predeterminedspeed; otherwisethe proper separation of the liquid into ts con- 1stituent parts willnot be obtained.

A further object of the invention is the provision of means to regulatesuch flow which shall be simple in construction, economical tomanufacture, composed of few parts, and unlikely to require iepairs.

In the accompanying drawings, I have illustrated .a preferredembodimentof this invention applied to a cream-separator, but it is to beunderstood that the invention is susceptible of employment inassociation with devices other than cream-separators.

In these drawings,Figure 1 is a fragmentary side elevation of a creamseparator supplied with my improved governor for controlling the feed ofliquid to the ma chineyFig. 2 is a view of the same mecha-. n'isrn atright angles to that of Fig. 1, and illustrates some or" the parts insection; F igs. 3, 4 5 and 6 are detail views illustrating thestructural features of the speed governor.

,By referring to the drawings, it will be observed that I haveillustrated my improved governing device in'connection with acream-sceparator of the usual-centrifugal type operated by means of ahandle 10. asso- .ciated with a shaft 11 geared to the other parts ofthe mechanism to obtain'sthe high speed of rotation necessaryforsecu'ring the proper separation of the milk'into ts component parts.As is customary with ma chines of this character, the one illustrated isequipped with a supply tank 12, from which the milk, when permitted, isadapted flow through a pipe '13 into the top portion '14: of theseparator. At its outer end, the pipe 18 is in communication with a ver-Specificationof Letters Patent. Application filed Maren 1s,

tical tube 15- the lower end 16 of which is tapered, as illustrated inFig. 2. This tube carries internally avalve 17 adapted by cooperationwith the tapered portion 16 of the tube to establish and breakcommunication between the tube 13 and the receptacle 14:.

The tube 15 also has Within it a plunger or guide 18 connected to thevalve 17 by a stem 19. The upper end of the tube 15 is equipped with asupporting bracket 20, on which is fulcrumed at 21 a lever 22, the endof which, disposed over the tube 15, is connected to the plunger 18 orstem 19 by a link 23, while the opposite end of the lever 22 isconnected to a rod v24 having at its upper end a hook 25 adapted toengage a pin 26 at the end of the lever.

The separator shaft 27 projects laterally beyond the base or standard 28of the machine, extending through an apertured boss 29 on the side ofsuch standard. This shaft has fastened thereto a plate 30, to theopposite ends of which are pivoted, on pins 31,

acted upon by centrifugal force, and when the speed becomes suihcientlyhighto overcome theretr'acting action of the springs 34, the weightswill separate, turning on their fulcrum pins 31, 31.

The outer end of the shaft 27 is journaled in a bracket 35, and betweensuch bracket and the plate 30 there is provided a sleeve 36 rotatablewith and also slidable on the shaft 27, being secured thereto by meansof a key 37 fitting in keywa'ys in the shaft 27 and the sleeve 36. Atone end, this sleeve 36- is equipped with a pair of disk portions 38 and39; between which are accommodated two pins 10, 40, secured to the cars32 or the two weights 33, wherebythe outward and inward swinging ofthese weights on their fulcrurn pins 31 causes a longitudinal shifting"of the sleeve 36 on its sup orting shaft 27.

boss portion 42 of the sleeve. One face of this boss section 42 isbeveled at43, and at its opposite end the sleeve 36. is provided with anoppositely beveled disk member 44. Be tween these two beveled surfaces43 and 44 another beveled disk 45 is accommodated,

such disk being cutaway on one side to'pro- Videa flat bearing surface46. The disk-45 is fastened to the inner 'e'n'dof a shaft 47 rev-foluble in a'bearing 48 fastened to or forming part of a lateralextension 49 of the bracket 85, At its other end, this shaft 47 has acol:

' lar 5O fastened thereto, to which the lower pivotally connected by aend of the rod 24 is screw '51.

' The operation of this governing 'mecha nism takes place substantiallyas follows:

Assuming that the supply receptacle 12 is charged "with milk and thatthe valve 17- prevents the flow of such fluid to the receptacle14by-coiiperating with the end 16 of the 'tube 15,,it will be obvious thatthe valve17 should not be perinitted to open until the speed ofoperatlon of the separator is su'ificiently high to"assure the properseparation of the milk into its component parts. The

operator, by grasping the handle l0 and reason the disk should attempttoturn in such direction as to open the valve 17, its

conical surface would at once contact with the surface 44, cqusing arotation of the disk 45 in a=directionbto close the valve 17. In

other words, so long as'the speed of rotation is below that which isadequate for the separation of the liquid, the valve 17 will bemaintained closed. Aslsoon -however, as,

the proper speed is reached, the outward swinging of the weights 33 inopposition to the retracting action of their springs 34 will, by means,of the coaction between the pins 40 andthe disks 38 and 39, slide thevalve 36 outwardly so as to bring the conical surface 43 into contactwiththe corresponding --surface of the disk 45, and, owing 'tosuchfrictional engagement, the latter disk will be turned, rotating theshaft 47 sufficiently to pull down the connecting rod 24, rock the lever22 on its fulcrum 21, and lift the valve 17 permitting the milk to flowfrom thereceptacle 12, through the pipe 18, into the chamber 14, fromwhich it passes down wardly into the centrifugal separator proper. Thevalve 17 will be maintained open so long as the speed of rotation'of themachine is up to or above the normal speed referred to. .That is to say,the disk 45, by'

being in direct engagement. If, however,

for any reason, the valve 17 should tend to close while the speed is ator above,the nor- ;lmal, the disk 45 would be turned slightly so as tobring its conicalfas distinguished 1 from its flat surface, intoengagement with jthe. surface 43, and by such frictional contact thedisk 45 would be turned back so as ;to.maintain the valve open and againre- 'turn the flat surface 46 opposite the conical surface 43. In otherwords, the valve 17 is mechanically and automatically maintained Q openso long as thespeed is proper. If the speed decreases so as to be belowthat which fis normal, then the inward movement of'the weights 33 willshift the sleeve 36 inwardly,

so that the disk 44 will engage the disk 45 j and turn the latterthrough 180 so as to close the valve and bring the flat surface 46 oposite the disk 44 when the valve is closed.

I t should be apparent, from the above description of the constructionand operation 1 of this mechanism, that the feed of liquid from thechamber 12 to the receptacle 14 is controlled solely by the speed ofoperation of the separator, and that the opening and closing of-thevalve17 is entirely automatic and mechanically accomplished. That is to say,the opening and closing of the valve s secured by the rocking Lof theshaft 47 in one direction or the other, and this turning of the-shaft isaccomplished'by bringing one or the other of the conical surfabes 43 or44 into contact with the disk 45," i-he speed of :rotation of themechanism determining -which of such conical surfaces shall at that timeengage the disk '45, the movements of the members provided with suchconical :surfaces being brought about by the action of thecentrifugally-controlled spring-retracted weights 33. In order tolimitthe v swinging of the collar or member 50 beyond.

the proper points,that is,'to zest-let its fniovement to 180-.-I providethe extension 49 of the bracket 35 with a pair of stop pins 521 and 53,against which the member 50 is adapted to bear in the opposite imits ofits oscillation. By employing a di k witn the flat or cut away part,there is=no resistance ofleredby the valve operating mechanism to theturning of the handle by the operator except during the opening andclosing movements of the valve. 9 I .W'hile'Ihave herein described thisinvention as applied to a cream separator, it is to b'e'iu'nderstoodthat the invention is susceptible of employment in many different artsand relations, andthat the structural fea- -tures of thepreferredemhodiment herein disclosed may be modifiedwithin comparativelywide limits without departing from the essence of the invention andwithout the sacrifice ofanyof its material benefits and advantages.
